The quotient, written in scientific notation, is equal to 2.5*10¹⁰
<h3>
How to solve the quotient?</h3>
Here we have a quotient between two numbers in scientific notation:
(2.275*10¹⁹)/(9.1*10⁸)
Using the associative property, we can rewrite the quotient as:
(2.275*10¹⁹)/(9.1*10⁸) = (2.275/9.1)*(10¹⁹/10⁸) = 0.25*10¹⁹⁻⁸ = 0.25*10¹¹
Finally, remember that we need to have a digit at the left of the decimal point, then to have the outcome in scientific notation:
0.25*10¹¹ = 2.5*10¹⁰
The correct option is the last one.

So for this, we will be simplifying √180 and √125 using the product rule of radicals (√ab = √a * √b)
Starting with √180: 
Now with √125: 
Now that we have our simplified radicals, our equation looks like this: 6√5 - 5√5 + √5 . Combine everything, and your answer will be 2√5.
Answer:
12/25
Step-by-step explanation:
There are 5 multiples of 5, 4 multiples of 6, and 3 multiples of 7.
5+4+3=12

Answer:
the sine of angle R is 5/7.
Step-by-step explanation:
Recall that the sine function is defined as sin Ф = (opposite side) / hypotenuse.
The side opposite Angle R is √65 and the hypotenuse is √91.
Thus, the sine of angle R is sin R = √65 / √91, or 5/7.
The anwser is 13 because the quantity increased by 1 is 14
